What I'm Seeing Now

The Basement Floor Slab In This New Home Is A Problem!

The basement floor slab in this new home is a problem!

What's going on with this floor?  It is only four months old.

The homeowners have been in the house for one month.

The basement is the indoor play zone for three small children.  There is a lot going on down there!

A week or so prior to this photo spots developed in one area of the floor.

During the next few days these spots grew in size.  The homeowners punctured one spot with a chop stick (!) and it opened right up.

The hole is about 1" deep and the goop inside smells like oil.

Of course they called me to ask if I knew what was going on.  My answer?  No.

So I went to the house to have a look, took some photos, went on the web, and asked some experts.  The bottom line is that nobody really knows, but the consensus of opinion is what I speculated on site.

The aggregate put onto the floor had a bit of oil in it, which globbed up, rested near the surface cream, and festered near the surface, finally producing stains.  The stains grew, and the area or cream immediately over each glob was very thin.

You can see from the photo that the largest stain was not very big at the time of the photo.

And by the time I saw it the goop had hardened, but could still get onto my finger, and it smelled like oil.

The builder was going to visit the house to see what was up.  I'm waiting to hear the report.

The experts on line also said what I thought at the time I saw this:  that area of flooring would need to be cut out and re-poured.  The slab is about 5" thick.

Still, more time needs to pass to see if there are any more areas which develop the stains.  They don't want to do anything until the entire scope of what is needed can be known.

My recommendation:  sometimes things don't happen at first in new construction!  But when they do it is best to consult a professional expert.  We don't know what we don't know.  And sometimes the experts don't know!  But still, get the best advice and go ahead.

Good morning Jay. This is bizarre and very very scary. Please do a follow up once your client finds out.

Thanks Anthony.

Freday - not bad!  I haven't heard back from the clients.  We'll see!

Sheila - no doubt.  I am interested.  But necessarily I would question anything the builder says.

Good morning Jay. This is definitely a problem that needs to be addressed by professionals. Hope the builder stands behind his product. Enjoy your day

Hi Jay- at first I thought it might be appropriate to call Jed Clampett!  Anyway, can't wait to read the followup.

Wayne - hopefully the builder will actually get a professional to evaluate this!

That's the size of it, Stephen!  But they just moved in here, Navy guy, with three children under 4 (twins).  I doubt they're thinking Beverly Hills, but I will suggest it!

S&A - the Beverly Hillbilly references are funny!  And just about right.

Kathy - the building "supervisor" came by and said he thought they should just cut out small areas around the spots and replace the slab there.  I asked my client if he was a concrete specialist!  Nope.  I think they need to wait until all the spots show up and replace the slab as a big chunk surrounding all them.  The problem is getting a pour that is as hard as the original slab!

Good time to have them cut concrete for the bathroom at no charge !

Those pipes and framing are already in, S&D.  And I am still waiting to hear the final answer as to what the builder will do.

Jay Markanich, I  would be interested in knowing out the outcome also the source of the stain.

Ritu - the builder's "expert" said it was something in the slurry (which was my theory) and that they were going to cut the area out and repour it.  I don't know what happened after that!  They haven't contacted me further.
